I would think if you can use regular yogurt you'd be safe with Greek yogurt too. I make a pork tenderloin where I use Greek yogurt and fresh dill to make the sauce that I put over the top. I thin the sauce with a little stock instead of any milk. I sear the pork on all sides, then finish it in the oven. While it cooks, I saute kale and add a can of diced tomatoes and a can of drained cannellini beans. Once the pork is done, I slice it and put it over top of the kale mix, then pour the sauce over it all. It's so good, and with all the veggies, you really don't need another side. But sometimes I'll make some pasta with pesto or something with it.
